WILLIAM H. Lu'rz, or PHILADELPHIA, PENNSYLVANLA.

To all whom t may concern.' Y

Be it known that I, WILLIAM H. LUTZ, a citizen of the United States-,residing in the city and county of Philadelphia, State of Pennsylvania,` have invented a new and use ful Quilting-Machine, of which the following is a specification.

The present invention relates to a machine for sewing together, generally in a fancy pattern the parts of a. quilt, comfort or covering of a like nature and has for an object to provide a supporting carriage for vthe quilt or like article, which is freely movable laterally in any direction and is underfthe control of a guide in the form of a pattern whereby a line of sewing may be worked on the quilt according to a predetermined configuration of 'any fanciful nature or otherwise. In the manufacture of quilts by machinery and according to given pattern designs it is necessary, in some instances, in order to properly and more expeditiously work the design upon the quilt, to provide two sewing heads instead of a single sewing head and another object of the inventionv is to provide means whereby the same machine mayv be readily converted from a single head single pattern machine to a double head double pattern machine.

A further object is to provide a'mechanism whereby the design of the pattern may be reproduced a number of times upon the same quilt and in consequence the pattern structure is greatly simplified.

It also has for an object to. provide a mechanism which may be adjusted for substantially any width of quilt made under ordinary standards and which mechanis'mis vertically adjustable to insure the proper placing of the quilt in alinement with the sewing head. or heads and shuttle table or tables.

It has for a still further object to provide a fixed or stationary support for the .sewing Y mechanism and its adjuncts whereby excessive tension of the quilt in its movement will not cause the sewing head support to be distorted and produce anirregular sewing'of the quilt as takes place where the machine is constructed with the sewing head machine mounted on. a movable frame.

ltfurther consists of other novel features of construct-ion, all as will be vhereinafter fullv set forth.

For the purpose of illustrating my invention, I have' shown in the accompanying QUILTINe-MACHINE.

Similar numeralsy of reference indicate corresponding partsy in the -iigures Referring to the drawings Y- l designates a pair ofstandardsf fiXedly secured. to the iioor or other suitable stationary base, Vandfprovi'ded respectivelywith pairs of tubular heads 2, whereby the' tubular members 3 and '4 are supported one above the other in parallel relation. These sectionv on line Y tively Xed supports for the sewing machine Vtables orbed plates 5 and thesewing heads 6. Since the-precise; construction of these tables, the shuttle mechanism 7 and thesewing heads 6 isl substantially immaterial and the purpose, a detailed description of their several parts is thought unnecessary. 'It

.will, however, be noted that both the tables 5 and heads 6 are mounted on their respective supports in such a manner as to provide' for adjustment longitudinally of the tubular members 3 and 4, while the heads 6 are in addition capable of independent rotary adjustment and therefore this construction will be described since it forms a material embodiment of the complete unitary structure comprising my invention.

8 designates the respective cross slides for the sewing heads and work tables, the same having rearwardly extending lugs 9 of suitable contour to conform to the shape of the tube members 3 and 4 and being fixed thereto by studs 10 or like fastening devices. The cross slides 8 are provided as usual with suitable ways or guide surfaces 11 to receive and support in sliding relation the guide ways 12 of the tables 5 and the heads 6, it being noted that a liner 13 or strip of metal is inserted between one guide way 11 of each cross slide and its component part so -that tightening of the set stud 14 xes the part in adjusted position. By reference to Fig. 2,

Y I Vit will be seen that the cross slides 8 are of suiiicient length' to permit a relatively wide range of adjustment for the tables 5 and headsV 6 transversely of the machine, it being understood that the heads are located opposite the tables in paired relation, that is to say, each head operates in conjunction with a table as will be readily understood. The cross slides 8 in each instance are-also preferably provided with suitable dowel pins 15 adapted to seat in openings formed in the members 3 and 4 in order to reduce the shearing strain on the studs 10 and furthermore insure proper alinement.

In the preferred embodiment of the invention there are three sets of tables and heads as shown in Fig. 2, the middle or single set being used for single head work Vwhen a single pattern is employed and the outer sets for double head work when a double pattern is used. In this latter type, the two heads operate simultaneously each reproducing the design or pattern traced by the other. For this purpose, I preferably provide a pivoted construction for the respective heads 6 so that the one or ones not in use may be swungto an inoperative position as indicated in dotted linesFig. 2. Each head in the present instance is fed from a thread cap 16 as will be apparent.

` 17 designates a frame (Figs. 7 and 8) fixed to the tube 3 by studs 18 for the purpose of forming a support and bearing for certain adjunctsofthedriven and control mechanism for operating the moving parts. Journaled in this frame 17 is a spindle 19 carrying thereon a pulley 20, which receives power from any suitable source and transmits it to a worm 21 and a bevel gear 22, the former beingY keyed or otherwise fixed to the spindle 19, and the latter secured by a set screw 23 or equivalent means. The bevel gear 22 is normally in mesh with a similar gear 24 (see Fig. 2) fixed to the shaft 26, the latter being suitably journaled in bearings 27 and extending from the central portion of the machine to one side thereof where it carries a. second bevel gear 28 which serves to transmit motion to the heads 6 and shuttle mechanism 7. This action takes place through the medium of bevel gears 29, 30 and 31, all of which are fixed to the stub shaft 32 and are respectively in mesh with the bevel gears 28 and the two gears 33. It will of course be understood that suitable brackets 34 are provided to support the Shaft 32 from a xed portion of the frame. One of the gears 33 is fixed to a spindle 35, located adjacent and parallel to the tube 3 and having the gear 36 loosely sleeved thereon to transmit motion to a gear 37 for actuating the shuttle mechanism 7 when the sleeve is clutched as will be later explained. The othery gear 33 is fixed in like manner to a shaft 38 which transmits motion to the sewing head mechanism by way of the sleeved gear 39 meshing with the gear 40 of the head driving means.

41 designates a plurality of clutch parts for controllingthe actuation of the respective sewing heads or shuttle mechanism, cach clutch part being preferably keyed for sliding movement to its proper shaft. Thus each of the shafts 35 and 38 carries, in the present instance, three clutch parts, each of which may be independently adjusted along the shaft and fixed in operative position by tightening its set screw 42.

The sleeved extension of the respective gears 36 and 39 carries a complemental part 43 of the clutch so that when the part 41 is moved into engagement therewith, then motion of the shaft is transmitted tothe gear to be driven. 44 designates a vertically disposed spindle mounted forsliding movement in the frame 17 and having a worm gear 45 keyed thereto and normally meshing with the worm 21 of the driven shaft 19. In this construction, the spindle 44 is provided with a relatively long key-way so that it is still in driving connection with the gear 45 irrespective of its position, this being an important detail as the controlling pinion 46 for engaging the rack requires to be moved up or down according to the position of the pattern and since it is fixed to the spindle 44 both must move together. The pattern rack 47 is shown in section in Fig. 8

with the pinion 46 `operatively engaging it.

collar 51i secured to the spindle 44. 52 designates a link to which the lever 48 is con n'ectedz and adjustment providedby means of a series of apertures 53 and. a pin 54. This link 52 isv secured to an arm 55 fixed to a rock-shaft 56 which is suitably journaled at 57 and 58 and extends to a convenient point, where it terminates in a hand-wheel 5 9, by which the parts are shifted as desired. In connection with the above described. movement'of the spindle 44, it may be stated that this shaft is only shifted from one position to another when the pattern is changed by superposing one on another.

Having now described those parts of the machine having a bearing more particularly upon the sewing head parts, I will now take up in detail the description of those parts which have to do with supporting, guiding and. carrying the quilt. r

.The quilt carrier mechanism and the movable v adjuncts thereof, in'y the present instance, are supported upon a carriage'60, which is preferably of sufficient length Yto l support apair of quilts, whereby it is possible for the machine to be working upon one quilt, while another one isV being positioned on the conveying mechanism ready to; be moved into/the machine as soon as the work on the first quilt has been completed. In

this type of machine where'the quilts are automatically fed int'o the machine, 'the overhang-or extension portionof the carriage 60 issupported for movement in any lateral direction by the'universally'jointed casters 6l, while thebody part of the carriage is provided with two'sets'of wheels 62 and 64. lPreferably one of these sets of wheels is provided with a groove 63 in order to straddle la suitable rail 66 mounted' upon an auxiliary carriage so that while the carriage `60 may move transversely of and relative to the carriage 65, a longitudinal mo-vementthereof will be transmittedto the auxiliary carriage and causeit also to move in therequired m'anner. The w-heels 64 areadapted torun upon a suitable flat rail 67 as-will be understood. The auxiliary carriage 65 in order to move as indicated, is supported upon wheels 68,- mounted upon rails 69 on the fioor'or othersupport, and arranged longitudinally of the machine, so thatthe quilt conveyingvmechanism not' only has 'a movement in a transverse direction, but also in `a longitudinal direction, since the carriage 60 may moveeither with the auxiliary carriage 65 or'relative thereto, as occasion demands. One of the rails 69 is preferably flanged to prevent improper movement of the carriage 65. 1

In view of the fact that the parts carried bytheicarriage 60 a'remore orless'heavy, es- 'p'eeially thepattern rack, it is essential that thecarriage supporting' face'V be suitably br'aced'tov prevent warping, and for that purpose I employ a plurality of channel bars 70, spaced at suitable intervals throughout the length of the carriage, as will be seen by' reference to Fig.5, while cross stringers 71: are provided for the auxiliary carriage 65 as will befapparent.` j h y 72 designates apluralityof tubular housings arranged in pairs and suitably secured, at desired intervals to the carriage 60, by means of bolts 73 or the like. Each of these housings serves as a seat for a pedestal member 74 having a bed 75 movably and adjustably mounted thereon, the said adjustment, in the present instance, being accomplished by means of a threaded bolt 76 passing through a leader nut 77 l fixed to the bed by set screws 78,while the saidbolt is xed to the'pedestal by collar members 79 and terminates in a square head 80 adapted to receive a. socket'wrench or the like for operating purposes. The bed is provided with a guide way 81, preferably of under-cut Aform to interiit with the guideway 82 of a supplemental bed 83, which is alsoprovided with an' upper guide way 84 to receive cer tain adj uncts now to be'described.

8 5 designates kan upright, fixedly carried adjacent one end kof each ofthe beds 83, and

serving as a bearing support for the spinelles-86 of the guide rolls 87. Thefends of the spindles 86 Vare journaled in standards Y 88, each of 'whichhas sliding engagement with the supplemental bed guide ways 84 so Vat either end'of the respective standards 88 and provided with right and lef-t hand screw threads 90Hand 91, which coact with-threaded bosses 92 of the saidv standards 88. A hand crank 93' is attached to each end of the rods 89 so that the parts may be adjusted from either side of the machine.

In order to affect independant vertical adjustment of the guide rolls 87, the pedestal members 74'each seat upon a stud 94 thread'- Y ed into the housing 72 and located in a 'suitable opening 95of the carrier platform 60. A locking nut 96 is provided for each stud for the purpose of fixing theparts in adjusted position. Y

Eachof the standards 88 carries a -stub shaft 97 mounted in-suitable bearings for edin pairs on Vthe respective guide roll lspin- Y dles 86 to rotate therewith for the purpose of conveying and supporting the chains 100 in their line-of travel along the upper portion of the machine'.

By reference to Fig. 2 of the drawings, it will be seen that there are twoY of these .chains 100, one at each side of the machine,

supported upon the sprockets 99 and extending longitudinally of the machine, there being, of course, as many pairs of standards 88 vas necessary to support the aforesaid chains. At suitable intervals throughout the length of the conveyer chains 100 there are clamping devices arranged in opposed relation for engaging or gripping the side edges of the quilt and holding it properly extended for the sewing operations. In the present instance, each of these clamping devices is fixed by screws 101, or the like, to lugs 102 forming a part of one link of the chain and the base member 103 of the clamp comprises a jaw 104 preferably formed by a transverse groove 105 and also having a pair of projecting wings 106, between which the movable jaw 107 is pivoted, as shown at 108. The jaw 107 is normally held closed by a spring 109 mounted on the pivot 108 and having its ends fulcrumed upon the ears 110' of the wings 106. Each base member 103 carries a roller 111 rotatably mounted on a pin 112 which in the present construction7 is clamped between a split portion of the member 103 by a screw 113. 'Ihe jaw members 107 are each, also, provided with a roller 114 carried by a pin 115 and laterally extending to bring the said rollers into a suitable position for engagement with a track mechanism now to be described.

In taking up the description of the track portion ofthe conveyer mechanism attention is directed to the fact' that in the preferred automatic type of machine there are two distinct sections, one being above the auxiliary carriage 65 and the other above that part of the carriage 60 which projects beyond the end of the auxiliary carriage 65. The former section of the machine is of Sufiicient size to accommodatea Complete quilt during the stitching operation, while the latter section is of similar dimensions and utilized for the purpose of positioning the quilt correctly on the conveyer before it is delivered to the operating part. Thus it will be seen that the quilts may be handled expeditiously, one being placed in position, while a second is being stitched and one operator can therefore readily take care of several machines.

116 designates a quilt supporting frame formed of slat construction which is sustained by means of rods 117 having sliding or t-elescope engagement with hollow posts 118 mounted on the carriage 60, the said rods being fixed in adjusted position by set screws 119, as will be apparent. The side portions of the operating section of the machine are fitted with side bars 120 located in the path of movement of the conveyer chains and having on the lower lface thereof a groove or guide-way 121 to receive the rollers 111 and on the upper face a track 122 which is yieldingly mounted by means of strip springs 123. These latter are preferably of corrugated form and normally hold the plate 122 above the path of movement of the lower side of the rollers 114 70 so that when the latter contact with the plate 122 the springs 123 will be placed u nder compression and reinforce the action of the jaw springs 109 to such an extent as to prevent the quilt from being pulled out or detached from the said clamping jaws. A Y bar 124 is secured tothe standards 88 'at each side of the machine, in order to suitably support the aforesaid side bars 120.

125 designates a cam track (Fig. 5) secured to the standards 88 at the ej ecting end of the machine and positioned in the path of movement of t-he conveyer chains 100 for the purpose of engaging the outer 'portion of the rolls 114, and thus automatically cause the jaws to be released as the quilt leaves the machine.

126 designates a rack pattern suitably secured to the carriage 60 and adapted to be engaged by the pinion 46 when the latter is lowered for the purpose of being guided by the single pattern. In some instances, it is desirable to employ a second pattern, that is one designed to simultaneously guide and control two sewing heads so that the pattern is reproduced in duplicate upon the quilt. 127 designates such a pattern rack mounted upon a base 128 and it is adapted to be removably supported above the single pattern rack as shown in Fig. 2.

By reference to Figs. 11 and 12, a modified form of pattern rack will be seen, wherein. a central partially rotatable pat- Vtern table 129 is employed in conjunction with the single head pattern. Thus the base 128 is recessed in circular form to receive the table l129 and the'latter carries a suitable pinion meshing with the worm 130. The spindle 131 of the worm extends to a convenient point where it terminates in an operating crank 132 as will be understood. Preferably the table 129 may only be turned through an angle lof sixty degrees as is indicated by lines A and B and to this end the stops 133 are employed which are engaged 115 by the pins 134 carried by the table. Thus in Fig. 12, after the center pattern has been worked in its position as indicated by line A, it may be turned to position line B and repeated in this position. In Fig. 14, I have shown a means whereby the number of sewing lines on the quilt may be varied at will by a simple rearrangement of the pattern rack. 135 designates a removable pattern section shown by way of example as connecting the outer and inner lines of the rack pattern so that the outer line of sewing is continuously with the inner line. In case the outer lines of sewin are desired to be separate from the inner lines the section y 130 may be removed and another section of suitable shape substituted to properly bridge the gap between the parts of the rack pat-i tern, The conveyer mechanismis preferably adapted to be driven at will from a belt 180 indicated by dotted lines on Fig. l.

In the operation of the machine, the quilt or other article to be stitched is first placed upon the table 117,6 with its side ledges in parallel relation to the conveyer chains 10.0. The operator next adjusts the clamp-ing devices 104 and 107 so that they grip the quilt along the edges and hold the samefast at suitable intervals and in stretched position between the chains. This position is of course determined by operating the handle cranks 93 to move the standards 88 toward or away from each other as the case mai be.

The proper rack pattern having been p acedl in position, which, in the present instance, we will assume isthe pattern 127, the conveyer chains are simultaneously operated vto move the article into position at the sewing section of the machine. In this position the rollers 114 have ridden upon the spring pressed rails 122, so that the clamping jaws are iirmly held against any tendency of the quilt to pull free and the machine is then ready to begin the automatic stitching op.- eration. lVith the power connected, the pulley 20 is driven to cause rotation ,ofthe pinion 46, which has of course, been moved. into engagement with the rack pattern 127, so that its rotation causes `the pattern to move thus shifting the carriage in one direction or the other ,or .causing the .table to move at rightV angles to this motion in either direction. There is therefore substantially a universal movement of the .quilt supporting devices, their direction of move# ment corresponding to the .contour ofthe pattern while the double sewing heads are reciprocating and each sewing a portion of the quilt. The pinion46 of course traverses the full length of the Arack pattern and when it has returned -to its initial position, .the quilt has beencompletely sewed Aand is ready for removal. Y f

During the sewing operation a second article has been placed upon the table `116V and iixed to the conveyer chain, so that when the completed quilt isf-ed out of the machine, the uncompleted quilt automatically takes its place as the quilt is delivered from the end of the machine, the rollers 114 of the clamping jaws run into the cam tracks 125 and are thereby automatically .opened to release the quiltV from theconveyer. e

It will now be vapparent that I have-devised a novel and useful construction which embodies the features of advantage enumerated las desirable inthe statementof the invention vand the above ydescription and while I have in the present instance shown and described ,the preferred embodiment thereofwhichl has been found in practicefto give 'satisfactory and reliable results, Iit is: to Y l be understood that the same issusceptible of modificationin various particularswithout departingfrom the spirit or scope of .the

tages. Y
